We wanted to create a Tea with a standardized dose, suitable for every body. It is now in a powder form because this is the safest way to deliver accurace and for the stability required to satisfy the Australian quality standards.
Part of the reason is that finely powdered herbs and herbal extracts leak out of the teabags. In the same way air can enter the bags and reduce the efficacy of the ingredients.
We chose the option of sachets filled with herbal extracts, as these are extremely good at delivering exactly the right dose and protecting the herbal material. The benefit is a consistent and reliable product.
